| Abstract: | Some novel reactive photochromic dyes containing mercury (II)-dithizonate moiety were synthesized from p-[(4, 6- dichloro-s-triazine-2-yl)amino]phenylntercur(II)dithizonate by using different aromatic amines and naphthalene intermediates for dyeing nylon fibres. The dyed fibre showed poor to good fastness to light, very good to excellent fastness to rubbing, and poor to good to very good fastness to washing. The dyed fibres on exposure to bright sunlight or a light source of suitable wavelength showed a very good photochromic effect giving various shades. When the fibres were/removed from sunlight the colour returned to the original shade. The duration required for this return depended on intensity of incident light, ambient temperature and moisture content of fabric. |
